Question
The following data are obtained from a tensile test of a copper specimen.
- The load at the yield point is 147 kN.
- Length of the specimen is 28 mm.
- The yield strength is 75 kN/mm2.
- The percentage of elongation is 49 %.
Determine the following
(i) Diameter of the specimen,
ii) Final length of the specimen,
iii) Stress under an elastic load of 16 kN,
iv) Young's Modulus if the elongation is 1 mm at 16 kN and
(v) Final diameter if the percentage of reduction in area is 22
Final Area of the Specimen at Fracture (in mm)
Final Diameter of the Specimen after Fracture (in mm)
Initial Cross-sectional Area (in mm2)
